the neutraized solution contains 1? grams of avallable chlorin per l1ter--a quantity Which We have often had in practice'hut which may vary according to the quality and freshness of the hypochlorite used.

For soaking the grain. is put into the usual soaking vats containing water to which 41.66 to 58.53 cubic centimeters of the neutral hypochlorite solution per liter have been added (this quantity being that which must be added so that the soaking water may contain 0.5 to 0.7 grams of available chlorin' per liter). After soaking six hours, the

Water, strengthened with the same amount of a neutral solution of hypochlorite, is re newed; after six hours the soaking Water is again renewed, always strengthened by the neutral hypochlorite solution; then the grain During the two periods of six hours as well as during that of 24- hours, sample of the soaking water must be taken every 2 or 3 hours and available chlorin must he put to it in order te bring he quality (tenor) up to 0.5 to 0.7 grams per hter. arsenious acid. Let us suppose that at the moment of testing it is seen that there is not more than 0.3 grams of available ehlorin )er liter in the ater; some of the neutral liyp'oehlorite solution should then he added in order again to obtain the 0.5 to 0.7 grams of chlorin per liter; The quantity to he added in this case would be 32.66 grams per liter of water. 7

According to the usual practice, the steep ing 0 oration is terminated when the corn is comp etely steeped, t. e, when the grain,

after being cut into two parts, will no longer show a while, mcaly, dry core. in my method, however, I. prefer to stop the steeping operation. while the corn is still. partially dry inside. The steeping operation is This testing is done by stopped after 12 to 24 hours in accordance. with. the ten'lperature and the degree of har'd nose of" the corn and is completed Onthe floor or in the stee ing trou 'h by sprinkling the neutral hypoo \lorite solhtion over the malt This sprinkling etleoted'during the whole preparation of the 1nalt--that is to sa in the period of 7 to 8 days during which the. malt remains on the malt floor, and at least once per da the solution thus sprinkled over the ma t contains 0.2 to 0.5 grams of available chlorin per liter. The more the germination advances, the more must the solution used contain chlorin.

Havin thus fully described my invention,

' what I c aim as new-and desire to, secure by Letters Patent is t 1. The process of preparing grain in the preparation of malt which consists in steepmg the grain in the presence of a neutralized hypochlorite salt, substantially as described.

2. The process of treating grain in; the preparationof nlalt which consists in stee mg the grain in water and adding to t 1e. steeping water a neutralized hypochlorite salt substantially as described.

3. The process of treating rain in the preparation of malt which consists in stee mg the grain in water and adding to tie steeping water from time to time sufficient neutralized hypochlorite salt totiuaintain the yield oievailahle chlorin at substantially 0.5 to 0.7 grams per liter of the water, substantially as described.

4. The process of treating grain in the preparation of malt which consists in steeping the grain in the presence of a neu'trah iced hypochlorite salt, terminating the steeping step before the grain is completely stee ed, and then effecting the germination oi t e grain in the presence at u neutralized hypochloritc salt, substantially as described.

n testimony whereof, I have signed my name to this specification in the presence of two subscribing witnesses.
